Structural Search and Replace

Structural Search and Replace (SSR) performs search and replace in the supported languages code across the whole project, taking advantage of the IntelliJ IDEA's awareness of the syntax and code structure of the supported languages.

IntelliJ IDEA finds, and if required, replaces fragments of source code, using the search templates.

Structural Search and Replace is helpful when you need to browse through or modify an extensive code base, find changes in libraries, explore the source code for specific constructs, or refactor the source code.
